To see the impact of each variations..
The different betting strategies :
Flat / 1,2,3,4,5,6 / 1,2,4,8 / 1,2,4,8,12 / 1,2,8,12 / optimal..etc
Using CVCX - bolded ramp should show a lower SCORE which should improve utilizing half true counts. As an example (adjust to "5.0 house edge) - you are even with the house at true 1, .5 he at true 2 and 3 units at true 3 - from true 2 to true 3, you’ve raised your bet by 1/3 while your margin has doubled which is clearly inefficient.

Also, you should compare each ramp against different deck pens and again v half true counts. If you can master these calculations, you should develop the necessary skill to ramp on the fly against different deck pens which translates to using different ramps at different deck penetrations.
